Read the passage about the Rosetta Stone. Before the Rosetta Stone was found, Egyptian history was lost to the world. The only clues were the mysterious picture writings that adorned temples and pyramids. For hundreds of years, scholars struggled to decipher these hieroglyphs. Then, in 1799, soldiers in Napoleon’s army stumbled on the Rosetta Stone.
